Patented Mar. 19, 1918.

Application filedMarch '2, 1917. Serial No. 152,162.

To aZZ whom it may concern:

Be it known that 1, CHARLES M. SWINGLE, a citizen of the United "States,residing at Cleveland, in the county of Cuyahogaand State of Ohio, haveinvented a new and use ful Cut-OE Valve, of which the following is aspecification.

One object of the present invention is to provide an exhaust pipe for anengine, carrying a valve which is controlled by a permutation mechanism.7

Another object of the invention is to improve the permutation mechanismper 36.

Another object of the invention is to provide novel means whereby, atthe will of an operator, an audible signal will be given when theexhaust traverses the exhaust pipe.

A further obj ect of the invention is to provide a novel means wherebythe owner of an automobile will be warned when his machine is beingtampered with.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andar'rangementof parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 shows in section, a device constructed in accordance with the invention, the cutting plane of Fig. 1being designated by the line 11 in Fig. v2;

Fig. 2 is a section taken on the line 2-2 of Fig. 1;

Fig. 3 is a top plan wherein the lid is open;

Fig. 4 is a section showing a modification; and

F ig. 5 is a fragmental section of the structure shown in Fig. 4, theparts having been shifted from the positions of Fig. 4.

In carrying out the invention as shown in Figs, 1 to 3, there isprovided a fixed plate 1 having a marginal flange 2. Upon its innerside, the fixed plate 1 is provided, near to its periphery, with a rib3. On the inner side of the fixed plate 1 near to the center thereofthere is a small rib 4, the ribs 3 and 4 being of annular configuration.There is an opening 5 in the center of the fixed plate 1. The fixedplate 1 has an eccentrically disposed opening 6 adapted to receive onepart 7 of the exhaust pipe of an internal combustion engine.

The invention comprises a fixed plate 8 having a marginal flange 9. Onthe inner side of the fixed plate 8 near to its periphery there isformed an annular recess 10. On the inner side of the fixed plate 8there is a smaller annular recess 11. The fixed plate 8 has a centralopening 12, and in the exterior face of the plate 8, about theopening12, a polygonal seat 14 is fashioned. The plate 8 has an eccentricopening 15. concentric with the opening '6 in theplate 1, and adapted toreceive a part 16 of the exhaust pipe. The plates 1 and 8 are united bya shaft in the form of a bolt 17 which holds the flanges 2 and 9 of therespective plates in abutment, as shown at '18. The bolt 17 has a head19 received against rotation in the seat 14 of the plate 8, the bolt 17passing through the opening 5 of the fixed plate 1. In the end oftheholt 17 there is formed an opening 20. The bolt 17 is split at itsend as shown at 21, so that said end of the bolt may be jyieldable.

Threaded in the opening 20 is a tapered screw 22 which expands the splitend of the bolt and causes the same to grip the plate 1 about theperiphery of the opening 5 therein.

The flanges 2 and 9 or the plates are cut away to form an aperture 23.Disposed on the flanges 2 and 9 at one end of the aperture 23 are spacedlugs 24 in which is pivoted an extension 25 at one end of a closure 26,the under side of the clos'ur'e 26 being equipped with a transverse rib27 Disposed on the flanges 2 and 9 arelugs 28 which are located closetogether. The closure 26 has fingers 29 extended along opposite sides ofthe lugs 28. The lugs 28 are provided with openings adapted to receive apadlock 30, so that the lid or closure 26 may be held in a closedposition.

Disposed between the plates 1 and 8 and journaled on the bolt 17 arepermutation disks 31. Each disk 31is provided on one side with anannular rib 32 and upon the opposite side of each disk there is anannular recess 33 adapted to receive the rib 32,

on anadjoining plate. Each disk 31 has, also, a large annular rib 34located on one face of the disk and adapted-to be received in asimilarly shaped recess 35 011 the opposite face of the next disk. Therib 32 on the outermost disk is received in the recess 11 of the plate8, the rib 34 on the said disk being received in the recess 10, the rib4 on the other fixed plate 1 being received in the recess 33 of theother end disk, and the rib 3 on the plate 1 being received in therecess 35 of the said disk. The disks 31 are provided with openings 36adapted to be disposed in coaxial relation to each other and in coaxialrelation to the openings 6 and 15 in the fixed plates. The peripheriesof the disks 31 are provided with notches 37 Numerals 38 are inscribedon the edges of the disks. These numerals38 are adapted to be alinedwith marks 39 formed on the end plates 1 and 8 on opposite sides of theaperture 23. c

In practical operation, the disks 31 may be manipulated by a suitablewrench (not shown), the wrench, coiiperating with the notches 37 in thedisks. When a predetermined set of numerals 38 is lined up with themarks 39, then the openings 36 in the disks will be alined coaxiallywith the openings 6 and 15 in the fixed plates 1 and 8 respectively, andthe exhaust can traverse the conduit '167. By a suitable manipulation ofone or more of the disks 38, some or all of the openings 36 in the disksmay be disposed out of alinement, and thenthe exhaust cannot traversethe pipes 7 and 16. It is to be observed that when the closure 26 isswung down onto the case comprising the plates 1 and 8, the transverserib 27' on the closure will be engaged in certain of the notches 37 inthe peripheries of the disks 31.

.ing closed.

A thin layer of graphite or other suitable substance, may be interposedbetween the ribs and the grooves of the various disks 31, and betweenthe end disks on the plates 1 and 8, so that the structure will begas-tight,

to an extent sufficient to make it operate.

In Figs. 4 and 5, a modified form of the invention hasbeen shown. 1

In the said figures, one end plate is denoted by the numeral 40, theflange of said plate being indicated by the reference character 41, andbeing provided with an aperture 42 corresponding to the aperture 23. Anexhaust pipe is shown at 43. The plate 40 has a slot 44 therethrough.orient the permutation disks is shown at 45. In addition, a disk 46 isdisposed adjacent the plate 40. The disk- 46 has a projection 47carrying a finger piece 48 moving in the aperture 42. The disk 46 isprovided with an opening 49 adapted to be alined with the exhaust pipe43. On each side of the projection 47, the disk 46 hasnotches 50. At thebases of the notches 50, recesses 51 are formed in the disk 46. Reeds 52are secured to the periphery of the disk 46 at the bases of the notches50 and coiiperate with the recesses 51.

Let is be supposed that thepermutation' 7 disk 45 has been so disposedthat the exhaust cannot pass through the structure from one endthereofto the other. Let it be supposed, further, thatthe disk 46 has 7been rotated by means of the finger piece 48 until the finger piece 48abuts against the flange 41 at either end of the aperture 42. Then oneof the recesses 51 in the disk will be lined up with'the exhaust pipe43. Under such circumstances, the exhaust from the engine, entering thepipe 43 will traverse the recess 51, actuate the reed 52, traverse onenotch 50, and pass out of the slot 44 in the I end plate 40. Theconstruction is such that an outlet for the exhaust is provided,preventing a bursting of the exhaust pipe, but,

. at the same time, an audible signal is given,

served that the finger piece 48 is provided with a notch 53 adapted toreceive a rib' 100 on the closurelOl. The structure shownin Figs. 4 and5 is the same as that described originally, savingfor the fact that theend plate40 has a slot 44, the disk 46 being added. e 7

Although the structure hereinbei'ore described is of peculiar utility onthe exhaust pipe of an engine,'the form shown in Figs. 1, 2 and 3 may beput on the supply pipe of the engine or elsewhere if desire Having thusdescribed the invention, what is claimed is 1 In a device of the classdescribed, a casing-having ports and provided with an aperture in itsperiphery; permutation disks journaled in the casing and accessiblethrough the aperture, for rotation, the disks having port's adapted tobe alined with the ports of the casing; and a lid constituting a closurefor the aperture and a protector for the disks, the lid and thepermutation disks having interlocking elements, coacting when the lid isclosed, to hold the disks in ad justed positions and against rotation.

2. In a device of the class described, a

easing having ports; permutation disksjournaled in the casing and havingports adapted to be alined With the ports of the casing; and anotherdisk journaled in the casing said other disk having a port adapted to bealined With the ports of the casing said other disk having an audiblesignal which is movable With said disk into operative rela tion With oneof the ports of the casing, the

10 casing having an outlet opening for the exhaust, after the exhausthas actuated the signal.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two Witnesses.
